Oura Ring 5 Cuts Size by 40 Percent While Boosting Battery Life, Ships at $399
Oura has introduced the Oura Ring 5, a significantly smaller wearable that also delivers longer battery life compared to its predecessor. The latest model arrives at a $399 price point and is available for purchase on Amazon and Target starting this month.
The headline change is the size: the Oura Ring 5 is 40 percent smaller than the Oura Ring 4. Despite the reduction in physical footprint, battery performance has improved. The ring now offers between six and nine days of use per charge, up from the five to eight days the previous generation provided.
Under the hood, the Oura Ring 5 retains the same photoplethysmography (PPG) architecture found in other health-tracking rings on the market. This sensor technology measures blood volume changes through the skin and is the foundation for the device's sleep, activity, and recovery tracking features.
What the Oura Ring 5 Size Means
A 40 percent smaller enclosure makes the Oura Ring 5 noticeably less bulky on the finger, which addresses one of the common complaints about earlier models. The slimmer profile may also improve comfort during sleep tracking, when users wear the ring overnight. Oura has kept the same core health tracking capabilities despite the downsized hardware.
At $399, the Oura Ring 5 matches the launch price of the Oura Ring 4. The company has not introduced any subscription changes alongside the new hardware. The ring ships in multiple finishes and sizes through Amazon and Target's online stores.
Battery Life in Context
The six-to-nine-day battery range puts the Oura Ring 5 ahead of most smartwatch competitors, which typically require daily or every-other-day charging. The improvement over the Oura Ring 4's five-to-eight-day range is modest but meaningful for users who want longer stretches between charges. The actual battery life depends on usage patterns, with more frequent heart rate and SpO2 measurements drawing more power.
The Oura Ring 5 enters a market that now includes the Samsung Galaxy Ring and Ultrahuman Ring Pro, both of which rely on similar PPG-based sensing. Oura's advantage has been its software platform and sleep tracking algorithms, which carry over to the new model.
With a smaller build, better battery life, and a familiar $399 price, the Oura Ring 5 keeps Oura competitive in the smart ring category during a period of growing interest from major phone makers.
